SPECFICATION forming pa1t of Lettera Patent No. 374.220, da.i :ei December 6, 1887.

Application filed October 12, 1887.

T0 ,aZZ whom il; may concern:

Be :it known that I, EDWARD WALTER, a citizen of the United States, residing at Keytesville, in the county of Ohariton, State of Missouri, have inventecl certain new and nseful Improvernentsin Pole-Yokes, of whieh the following is, a specifieation, referenoe being hard therein to the aeeompanying drawings.

This invention relates to improvernents in poleyokes for cnrriage and wagon poles, and among the objects in view are to reduce the weight, yet stiffen and strengthen the saune, and this at a minimum cost of manufactnre, and also avod ali vertical oscillation.

Other objects and advantages of the invention Will hereinafter appeal, and the novel features thereof will be partioularly pointed out in the claims.

Referring to the drawings, Figure 1 is a rear elevation of a pole-yoke constrncted in accordance with my invention; Fig. 2, a plan; Fig. 3, a front elevation; and Fig. 4, a perspective in deta.il, hereinafter more partioularly described.

Like letters of referenee indicate like parts in all the figures of the drawings.

In practieing my invention I provide a casting, A, of metal, whch is of snbstantially X for1n and comprises upper and lower plates, A, eonneeted at their front by a. transverse plate, A, and at tbeir rear by short plates A forming, in connection wth the npper and lower plates, A, sockets A. Bolt or rvet holes A are formed at the ends of the plate A, and similar holes are formed in each of the sbort plates A The upper and lower plates are provided with perforations A, into which is swiveled the pole-soeket B by means of lugs or trunnions B enterng said perforations. The pole 0 is entered in and seoured within the socket by any sutable n1eans, and as thus clesoribed it Will be seen that the pole and its'socket have ai PVOILI connection With the X-shaped casting A,

If desired, and in order to permit of a, vertieal oscillation of the yoke. independent of the pole, as in eases where the horses are working unevenly, I may provide the soeket B wth a transverse slot, B into which 21 pin, 0, promay also serve to retain the pole within its socket.

Serial No. 252,159. (No model.)

.D represents light wooden strips, or, if desired, they may be of metal, the inner ends of whioh are bolted within the sooket ends A of the casting A, whch strips are curved or bent a11dpreferably tapered, so as to terminate at a line drawn through the center of the casting A, at whieh point tl1eir ter1ninals are connected to a longitudina'l strip, E, by means of ferrules or thimbles E, said strip being bolted to the front plate, A 01 the casting A. This strip, like the short strips D, may be of either wood or metal, and f of the former a light metallie strip, F, may be seeured to its front face, the ends of which terminate in a loop, F, by which the yoke may be secured to the horse-collars by the usual pole chain or strap.

If desired, the center piece, A, may be formed of sheet metal and not of cast, in whieh case the several plates eomposing the same may be formed independent or integral, as found most eonvenient.

From the above description t is evident that a liglit and strong single or clouble tree can be constructed after 1ny invention, the onl y ehange required being to omt the soeket.

Havng describecl my nvention, whatI elaim 1s- 1. Thecombiriation, inupoleyoke, of aoasting provided With rear sockets and a front securing-plate, and strips secured in said soekets and to sad plate and united at their ends, sub stantially as speeified.

2. The combination, in a pole-yoke, of a cn tral oasting formed With a front securing-plate and rear end socket's, strips seeured in said sockets and to said plate united at their ends,

and a pole-socket seonred Witbin the oasting,

substantially as speoified.

3. The combnation, in a pole-yoke, of a cen trai substa'ntially X-shapecl easting formed Witl1 remend soekets and a front seeuringplate, strips secured within thesockets and to the piatte, ferrules for seguring the ends of sad strips, with a polesooket mounted for pivotal movement in saicl easting, substantiall y as specified.

4. The easting A, comprisng the upper and lower plates, A, the front p1ate, A the rear plat'es, A forming the sockets A", in con1b- 112LOD With the short strips D, seeured in said soekets, and the long strip E, said strips being conneoted by the ferrules E, and the metal facing-strip F, secured to che 1ong strip and beni; ab its ends to form loops F, substantially as specified.

5. The casting A, formed W1 the socketa ends A and securingplate A and p'rforated, as ab A, the strips D and E, connected as described, in cqmbination wbh the socket B, baving the trunnons B to enter said perforatons, and the pole C, mounted in the socket, sub stantially as specified.

6. The casting A, provided with the rear sockets, A, and front securing-plate, A, lahe strips D ami E, connectedthereto and to ea'ch other, as described, in combination Wibh the pole-socket B, pvoted within sad casting and 15 provded Wth the slot; B, and the pole C, mountedin the socket and provided with pin 0', adapted DO enter the slot, substantially as specified.

In testimony whereof I affix my sgnature in presence of two witnesses.
